Learn to operate the Artisan's Asylym Bridgeport Series I Computer Numeric Controlled (CNC) milling machine. CNC milling machines can be used to make parts that would be difficult or impossible to machine manually. CNC milling uses build files to control the machines movements, which makes machining multiple copies of the same part easier and more reliable.
This class focuses on operating the Bridgeport CNC milling machine, recently rebuilt using a LinuxCNC control system. (LinuxCNC is an open source motion control system, used in a wide variety of machines. AXIS is the most common interface used with LinuxCNC.)
Students will learn:
using the machine controls, including the standard LinuxCNC AXIS interface
loading G-code build files and previewing tool path information prior to run
using Kwik-switch tool holders and ER collets
setting tool length offsets and work offsets in LinuxCNC using a touchoff probe
setting tool length offsets and work offsets in LinuxCNC using conventional measuring devices, such as an edge finder and Z-setter
running G-code build files and making adjustments during the run
troubleshooting common problems with the machine
Students will get hands-on practice with the machine during the class, using instructor provided build files, tools and material.
After completing the class, students will be required to schedule a testing session with the instructor and demonstrate they can operate the machine safely. Students must provide their own build file, tools and materiels for that testing. After successful testing, students will be allowed to use the machine independently.
Students must be at least 18 years of age.
Students MUST be checked off to use the manual Bridgeport milling machines at the Asylum prior to registering for this class! If you have not checked out on the manual Bridgeports, you will either have to take the Tool Training: Manual Milling Machines class, or request a test out.
We will not be covering how to create the G-code build files used on this machine. In order to use this machine to create their own part designs, students should be prepared to take additional classes at the Asylum or have comparable experience with:
Intro to SolidWorks (for CAD part design) or other CAD experience
Intro to HSMworks (for CAM operations) or other CAM experience
Manual Machining and Layout, or comparable machining experience
It is preferable, but not required, that students take these other classes prior to or concurrent with taking this tool training class.
All materials for the class will be provided.
What To Bring:
Hair ties for long hair, no loose clothing, closed-toed shoes.
This class will not run with fewer than 2 students.
